Thanks, joshwex90.

So your outbound is marked Y+, meaning that you are allowed 2x23. With regards to the on-line booking and based on my experience with AZ, you can be sure that, even with a screen-shot in hand, they will strictly refer to the general policy and tell you that you are only allowed 1x23 hence, as wrong as it sounds, go for the latter and get your journey off to a good start. AZ customer services [& IT] are simply pathetic (EY will have plenty to do in that respect), however I am pretty sure you will enjoy the experience on-board.

Best,
